It's important that each of us realizes our roles in helping to prevent or solve crimes in our homes and neighborhoods.

Yesterday, the Guam Police Department credited a Neighborhood Watch program for a tip that led to an arrest in a case involving a woman who was allegedly sexually assaulted during a home invasion.

Those who have information about crimes have a civic responsibility to share it with officers of law enforcement agencies. And that goes for all crime, be it sexual assault, burglary, vandalism or child abuse -- even if those involved are family or people you know.

There are a number of things residents can do to make their homes safer.

•People can install deadbolts and ensure that they keep all their doors and windows locked at all times. Homeowners also could plant thorny bushes below windows, keep a dog on the property and install exterior lights that turn on when motion is sensed.

•If you can afford it, the installation of a home security alarm and hiring of a private security company can provide a higher level of home protection.

•Most criminals are opportunistic and look for homes that are easy to break into, so the more difficult or dangerous it is for a criminal to try to enter your home, the more safe your house and valuables will be.

•But one of the easiest measures you can take to prevent crimes in your home and neighborhood is also one of the most cost-efficient -- being a good neighbor.

Get to know the people who live near you, and work together to make the neighborhood's homes better protected. If you see suspicious activity in your area, call it in to police. If you have information about a burglary or other crimes, call Crime Stoppers.

You can even formalize things by setting up an official Neighborhood Watch program. You can tap your village mayor and local police precincts to find out how to accomplish this. Police can't be everywhere. Neighbors who band together to work with police help protect their community from criminals.
